J. 120V AC Power
There are three power sources for the Back Cove 30
standard 120V, 60Hz, alternating current (AC) power
system: shore power (see Fig_6.2-9), the generator
(optional) (see Fig_6.2-10), or the inverter (optional)
(see Fig_6.2-11).
Treat all 120V AC electrical system components
and wiring as potentially energized. All potential
sources of power (shore power, inverter and
generator) must be
servicing. Only technicians fully trained in ABYC
and other applicable standards should service
the electrical systems.
K. 120V AC Electrical Distribution Panel
(Fig_6.2-4)
The 120V AC section of the electrical distribution
panel on the Back Cove 30 is located on the
bulkhead aft of the galley on the starboard side. (see
Fig_6.2-4 thru Fig_6.2-6) The standard panel is
designed to distribute the available 120V AC power,
either from shore power or the optional generator to
the appropriate branch circuits. Power is fed to it
through ELCI/RCBO (Equipment Leakage Circuit
Interrupter / Residual Current Breaker with Overload)
breakers located on the aft bulkhead in the engine
room. (see Fig_6.2-18) The ground runs through an
isolator (see Fig_6.2-18) which is a diode engineered
to block the flow of small stray DC currents. This
isolates the 120V AC system ground from the dock's
power supply.

AC Electrical Sub Panel

The AC sub panel distributes power to the helm deck
AC outlets, cabin AC outlets and microwave oven.
(see Fig_6.2-6). This panel is supplied by either the
optional inverter or the sub panel breaker on the AC
electrical distribution panel.

L. Standard Shore Power Operation
(see Fig_6.2-9)
(Fig_6.2-9)
Always connect the shore power cord to boat
then to shore. Turn shore power breaker "OFF"
before connecting.
Always connect the shore power cord with all
circuit breakers in the 120V AC section of the
electrical distribution panel, and all 120V AC
equipment, "OFF".
inverter, if installed.
After connecting shore power verify that the polarity
and voltage are correct by reviewing the reverse
polarity light and voltage gauge on the panel. Turn
ON breakers for each of the systems that need to be
energized.
Deactivate the optional
